Abstract
The utility model relates to an downthehole keyway symmetry dipperstick, as figure 1, it is by main scale , vice chi (2) and vernier (3) are constituteed, it is main, the vice chi is inserted respectively violently on vernier (3), indulge in two mutually perpendicular's spout, and can make relative movement along the groove separately, rely on the size scale on this kind of structure and main scale , it can not need other annex, conveniently correctly carry out the symmetry to the downthehole keyway of various specifications and measure, the method of the downthehole keyway symmetry of keyway clearance fit measurement with vernier caliper and multiple specification at present has been changed.
Description
The utility model belongs to vernier class dip stick measurer class, especially the female keyway symmetry dip stick of being made up of main scale, secondary chi, vernier.
Known vernier class dip stick, mainly be the internal diameter that is used to measure axis hole, external diameter, hole, groove depth, workpiece height etc., be that keyway feeler gauge with vernier caliper and corresponding specification is used and measures when being used for measured hole internal keyway symmetry, during measurement this feeler gauge is inserted keyway, measure the ultimate range of keyway feeler gauge side to hole wall respectively with vernier caliper then, two are symmetry apart from difference." digging, insert worker's technology " the 266th page of introduction of a book of the book number ISBN7-111-07313-4/TG.1331 that China Machine Press in July, 2000 publishes be exactly present general measuring method.Because when using common calliper to measure female keyway corresponding to different size, keyway feeler gauge that must the corresponding specification of adapted has increased the detection cost, and measures and need proceed step by step, and during operating cost, the product that is not suitable for the many specifications of short run is especially measured.
The purpose of this utility model provides a kind of female keyway symmetry dip stick, and it need not the keyway feeler gauge, just can measure the female keyway symmetry of plurality of specifications easily.
The technical scheme that the utility model adopted is: form one dip stick by main scale, secondary chi, vernier, two perpendicular in length and breadth chutes are arranged on the vernier, main scale is inserted in the translot, vernier can rely on the guide effect of translot to move horizontally on main scale, secondary chi is inserted in the pod, and can move up and down along pod.The length dimension of being carved on the main scale be respectively from the two ends of main scale to the third side to progressively increasing progressively, also indicate size scale on the vernier.Earlier this dip stick is put into during measurement and treated gaging hole, the sliding pair chi is adjusted main scale to keyway one side, makes secondary ulnar surface be adjacent to keyway one side, and reading moves to the keyway another side with secondary chi again, reading, and two numerical difference between promptly are the symmetries of keyway.
In this technical scheme, because the major-minor chi is inserted in respectively in two chutes in length and breadth of vernier, the major-minor chi is a kind of orthogonal position relation, two chis all can relatively move in chute, can satisfy the width dimensions of female keyway to be measured like this, can satisfy at the bottom of the keyways that cause because of the aperture is different depth location relation again with respect to main scale, therefore, this dip stick can satisfy the measurement of the female keyway symmetry of different size, need not the keyway feeler gauge, and after this dip stick mixes up, only need secondary chi is moved the position twice, just can obtain measurement result, method of operating is easy.
The utility model is described in further detail below in conjunction with example.
Fig. 1 is a principle assumption diagram of the present utility model.
Fig. 2 is the vernier cut-open view of Fig. 1.
As shown in Figure 2, main scale (1) inserts in the translot (4) of vernier (3), and vernier (3) can move horizontally along main scale (1), and secondary chi (2) inserts in the pod (5) of vernier (3), and secondary chi longitudinally groove (5) moves up and down.Shown in figure (1), during measurement female keyway symmetry dip stick put into and treat gaging hole (6), promote vernier (3) it is moved horizontally, promote secondary chi (2), it is moved up and down, make secondary chi (2) be close to female keyway (7) one sides, make the inwall of the both ends of the surface of main scale (1) simultaneously near hole (6), reading, fixedly main scale is motionless with hand, promotes vernier (3) again, makes secondary chi (2) be adjacent to the opposite side of female keyway (7), reading, two number differences promptly are the symmetries of keyway (7).
Certainly, this dip stick also can be used for the measurement except that keyway symmetry.
Claims (2)
1, a kind of female keyway symmetry dip stick is made up of main scale (1), secondary chi (2) and vernier (3), and it is characterized in that has pod (5) and translot (4) on the vernier (3), and two grooves are orthogonal position relations.Be inserted with secondary chi (2) in the pod (5), be inserted with main scale (1) in the translot (4), secondary chi (2) can be for vertical movement along pod (5), and vernier (3) can move horizontally along main scale (1).
2, female keyway symmetry dip stick according to claim 1 it is characterized in that on the described main scale (1) length dimension being arranged, and its length value increases progressively to the center from two ends.
